. SPECIFICATION forming part of Letters Patent. No. 266,889,vdatedEQctober 31, 1882.

' Application filed September 19, 1882. (No model.) i

Be it known that I ELIAS zen ot' the United States, 'residing'at- JerseyCity, Hudson county, 4I lew .Jcrsey, have in vented new and usefulImprvementsinGas- Burners,`of which the following is a'specilication.

The objectsof -this invent-ion areto insure strongupwardIy-induced'currentsof airaround the top of a gas-burner. and todeflect the said air-currents Vtoward the flame from all sides,V

so as to perfect combustion', also,to induce strong upward currents ofair around the gasburnertip, sc as topromote combustion and intensifythe heat, whereby a surface of p1ati. num presented to `the flame willbe rendered highly incandescent;l also, tojprovide one or moreburners'with'certain attachments where'-v by a strong draft isproduced,and at the same time a steady light maintained. To such end Iemploy, in connection with the gas burner or burners, the attachmentshereinafter described the annexed drawings,inf

and illustrated in which-A Figure l is a section taken ou a Verticalcen-.-

tral plane through a gas-burner provided with my improved attachments.'Fig'. 2. is a like section of a modified form of construction. Fig. Sisa detail sectional view of a 'portion of Fig. 2 onafreduced scale. Fig..4= is a plan or top viewof the detlector G, shown inFig. 1. Fig. 5 is asection taken on a verticalplane through a multiple burner yprovidedwith attachmentsof a somewhat modified form, bt involving the sameprinciples of construction as the attachments shown in Figs. l and 2.Fig. 6 is a top-or plan view of Fig. 5, and Fig.

i' is a plan 'view of the under side of the per.

forated jacket shown in said figure.

Referringby letter toFig.-1of the drawings, A iudicatesthe base or bodyof lthe burner,

which is adapted to be connected with van ordi-Q.

nary supply-pipe. Bindicates a perforated cup-shaped jacket, which isfitted upon the upper end of the body of the burner, connecf tionbetween the said two parts being prefer-v ably made by screwingthe'burner-body into an internally screw-threaded sleeve, which isformed at the bottom of the jacket around an opening through whichtheburner-body passes.

. The globe or chimney()` rests upon a perforated rest orsupporting-plate, D, which is provided B. REQUA, a oniat its rim with aiiange, E, and `with-a thumbscrew, F,'for the purpose of securingthechimney upon the plate. The plateisfsecured upon the perforatedjacket, and is preferably formed 4in one piece with the deectorG,.which`serves to direct the upwardly-induced currents of air aroundthe tip and against the base of the frame 'from all. sides. 'lhe upperportion of this detlector is contracted Yand provided atits.

top with an opening,H,for thepassage of the flame. The burner-tip Iextends within the said upper contracted portion of thedeiiector,and'has its body K, which is made somewhat longer thanusual, secured inthe upper end of the body ot' the burner. lIt will be observed, however,that this body K, which is below the tip proper, practically constitutesa portion of the burner-body which extends within the perforated jacket.

When the burner and. its several auxiliaries are constructed andarranged as above-dcscribed, it will be seenthat by reason ofthe up.-ward draft through thechimney and of the draft through the passagebetween the tip and jacket, and thence pass upwardlyaround the tip totheopening H in the top ofthe detlector.

The walls ofthe detlector will direct the air `against'the baseoftheflame, and by reason of its upper contracted form induce a strongupward current, which will increase the ilame and intensify the heat.The upwardly-induced currents of air through thejacket and the passagethrough thedeiiector are indicated by arrows, an arrow being' alsoemployed to indicate the upward current of air through the globe orchimney holder, which latter being perforated will admitair withinthechimney, andalso allow the light to shine below the burner.

While in Fig. 2 the principles of construcltion are the same as in Fig.1, the form of sme of the burner attachments is slightly different-as,for example, while in Fig. 1 the plate Iforming the chimney-supportandthe deflector is concave-convex or bell-shaped, with itsirregularly-shaped concavity ou the under side, in Fig. 2 the annularconcavity ot' the chimneysupporting plate is onthe upper side and thedeilector G made somewhat similar to an ordif IOC nary cone-deector.This deiiector unites with4 v `2c jacket and below the oritlce t theconcaved or flaring chutney-,supporting l, plateat or about the lineofconnection between c provided at the top with a slot or opening,- H,

and the burner-tip is located withi-n, thede.

Hector, so that the walls ot' the latter will dellect theupwardly-induced currents of air against the baseot' the llame. ln lieuof elongatin-g -the body of the tip, as in Fig. 1,'it is made ofordinary size and the upper end of the burner-body extended up to apointwhich is above the perforated portion ot the jacket'.

ln either case,fhowever,the result is the same,`

since in both instances the burner-tip, which is inclosed within achamber formed by the pertoratedjacket and the superposed deflector, islocated above the perforated walls ot' the at the top of, the deiiector.

In Fig.l 1,-L indicates an inverted basket or hollow frameofplatinum,supported within the globe or chimney and over the burner-tipby means of rods -M, which are secured at their lower ends to aconcavoconvex plate, N. This plate is held in place over the deiector Gby vertical supports 0, connected with a collar, P,-

which is fitted around the upper contracted portion of said detlector.This plate N is providedwith a central aperture, Q, for the passage ofthe flame which issues trom the aperture in the top of the deflector G,and it serves as an upper auxiliary detlector for inducing and directingagainst the llame a current from the surrounding air within the chimney,as in- I ,dicated by the arrow q. The flame will heat the platinumbasket or frame, which, upon becoming incandescent, will emit abrilliant light, and thus add greatly to the light from the flame. ,o l.t

In the construction shown in Fig. 2two pair of rods or supports, M, willbe respectively located on opposite sides ot' the dellector. These rodswill be connected above thel deflector ,by carbon wires or cross bars m,(shown in cross-section`,) thereby forming` the carbon frames L inplanes parallel with the sidesot the flame. Y

Referring now to Figs. 5, 6, and 7, which illustrate a multiple burner,such as shown and describedv in Letters Patent granted to melon the 29thday of August, 1882, and therein eX- pressly stated as forming no partof said paten t', but reserved for a subsequent application,- Aindicates the base or body of the gas-burner, which is provided withasingle lower pipe, a, the latter being adapted iu any suitable way toconnect with the supply-pipe, and being considered as a part of theburner-body. The burner-tips I are either formed with or secured to saidburner base or body, and'each tip is surrounded by a dctlector, G, whichis in the form of a truncated cone. The perforated plate D, forsupporting the chimney C, is also adaptedto support a glassllame-protector, It, having a slot, r, parallel with the line ofPdellectors. The ilame-protector rests upon an annular seat, di, formedby a horizontal ilange of plate, D', while the chimney 7o C rests upon alower annular lip, cl2, between an annular vertical portion, d3, of theplate and its marginal flange E. The plateD is perforated between thedellectors and the ameprotector It, and the vertical portion d3 of said7 5 plate is also perforated,-as shown. The perforated jacket B restsupon and is supported by part tof the burner-body, and is Aconnectedwith plate D, so as to support both said plate and the d'ele'ctors. Theplatinum in this in- 8o stance is preferably made into the form of auoval-shaped plate,y L` concavert in cross-section and provided withperforations or slits. This strip has at its ends the supports M, whichcan `be fixed at their lower ends in any suitable 8 insulated blocksfitted in tubes or sockets secured to the end deilectors of the series.The upwardly-induced currents of air in the lastdescribed constructionpass through the perforated jacket, and thence up and around the 9e topsto the llames,` the dellectors performing thc same service as thatdescribed ineonnection with the other figures.. Air will also enter thespace between thcchininey and the flameprotector through the perforatedportion d3 of Iplate D, while air will also pass up into the' spacebetween the detlectors andthe liame-protectors through the perforationsin the flange d of the said plate.

Having thus described my invention, what 1o I claim is 1. Thecombination, substantially as hereinbefore described, of the perforatedcupshaped jacket B, the conical deliector G, secured over. the same, theperforated base-plate D,forming 1o 5 a chimney-rest, and a gas-burnerthe body of which projects into the chamberl formed by the jacket andthedelector and is provided with I a gas-burning tip terminating at apoint beneath the top portion ofthe dellector, where-:11o by theintlowingeurrents of air are directed onto the base ot' the gas-llame onall sides beneath the top portion of the deliector, substan tially asdescribed.

2. The combination, substantially as herein- I '15 before described, ofthe perforated cup-shaped jacket \B, the conical dellector secured overthe same, the perforated base-plate forming a chimney-rest, a gas-burnerthe body of which project-s into the chamber formed by the jacket 12oand the defleetor,and is provided -with a gasv burning tip terminatingbeneath the top-portion of the deflector, and aplatinum' structure t'supported above the dellector in the plane of the ilame issuing-throughthe slot therein, as set forth,

The combi-natiomwith one or moregas-1 burner tips incloscd bydeilectors, ot' a perforated strip of platinum supported above thedetlectors bymeans of intermediate connec- 13o tions, the body of saidburner beingsurrounded by a perforated jacket which is litted to itsbody portion, whereby air entering the jacket will pass upwardly throughthe deilectors so 266,889' v Y a as to feed the flames and therebydevelop-.'burner-tips being nclosed within the delectxof greater heat;for rendering lche platinum incandescent, substantially as described.

4. The combination, with .the body of a gasburner provided with one ormore tips, of a. combined chimney-supporting plate and deljectorssupported byaperforated jacket: which is ttcd to the burner-body and aplatinum structure located above the deflectors, the

ors above the perforated jacket, substantially i.

as described. In testimony whereof I have hereunto set my hand in thepresence of two subscribing,r witnesses. y
